Just unscrew the MAP sensor you have from your throttle body and zip tie a hose to the nipple on it. Connect that to a manifold vacuum source and roll.

If you want a cleaner install, get a MAP sensor off of an old DX. Most of them are already set up like that instead of being screwed down to the throttle body, and the hose barb on the sensor is much easier to work with.

and ^^^ what he said... B-series manifold won't fit a D-series.
